An unusual and evocative ring set with a Spanish colonial silver cob coin, dating to the late 17th–18th century, later mounted in a 14K yellow gold ring, likely crafted in the United States in the 70’s. 

The silver coin, approximately 17mm in diameter, is a Spanish colonial reales silver coin, minted in either Peru or Bolivia. Known as “cobs” due to their irregular, hand-cut shapes, these coins were struck hastily but to strict weight standards. They feature the distinctive cross-and-shield design: here, the cross of Jerusalem divides the coat of arms of Castile and León, with two rampant lions and two castles clearly visible. Though the date and denomination on the other side of the coin are partially obscured, the coin remains a fine example of the type, rich with historical resonance.

Spanish colonial cobs circulated widely throughout the empire and beyond, becoming the principal currency in transatlantic trade and frequently turning up in shipwreck hoards. Their association with piracy and privateering has cemented their place in maritime lore. This coin, almost certainly recovered from a shipwreck, was set into a heavy, wearable gold mount during the 1970s, a period when treasure finds set in jewellery were particularly fashionable.

The ring is stamped with a French ‘st. Jacques’ import hallmark for 14K gold alongside the French swan hallmark for silver, indicating its later entry into France.

A ring that bridges Spanish imperial history, shipwreck lore, and 20th-century treasure-hunting culture - a striking jewel for collectors and adventurers alike.
